i always thought  routed out sides were the strongest way to build the cab but my carpenter seems to think that if he used buiscets and screws it will hold just aswell. However he is not a cab builder. i dont know any cab builders so was wondering if any could let me know

alot of people will argue a fully rebated cab is alot stronger but IMO a butt jointed cab is just as strong i not stronger

basically the more surface glue area the better

so take a rebate joint........18mm at the end, plus say.....7mm deep? so now we have 18+7+7= 32mm glue area instead of 18mm glue area

some people rebate 5mm, but that's still 28mm glue area

Regardless of glue area the joint cannot be any stronger than the parent material, when the joint fails which gives? I have never found a glued joint to fail regardless of joint type it has always been the material away from the joint.

Rebated joints are probably more resistant to axial loading but you should not have any of those in cabs that have been braced correctly.

You can also make the joints much more air tight with rebates smothered in glue.
